In over 85-90% of cases one single laser treatment is sufficient. In others, a second laser treatment is necessary to help you achieve the optimum vision. At BoydVision your laser vision correction is covered for retreatment up until 5 years after surgery. After that there is a fee for any further follow up visit, but you are eligible for retreatment at a reduced fee ($395/eye) indefinitely, as long as it is medically safe to do so. Blended Laser treatments are separate than regular Custom Laser Vision correction, and have a separate fee charge.
